Drow are actually one of the strongest races in EA currently. Their big disadvantage, sunlight sensitivity, is completely removed. And they keep their superior darkvision and powerful spells. Dancing lights isn't great, sure, but faerie fire and darkness are excellent and almost any class would appreciate having them available.
I'm really hoping we get Duergar and deep gnomes as well, since, from an implementation point of view, it's just some different skin colors on existing models. Duergar get enlarge person which is a lot of fun. 8 foot tall dwarf fighter once a day.
